摘　　要：根据FRP筋混凝土双向板的弯曲破坏特征,引入FRP筋名义屈服强度和FRP筋有效截面面积的概念,对板中局部均布荷载作用下的FRP筋混凝土双向板的受弯承载力进行了塑性极限分析,提出了FRP筋混凝土双向板极限受弯承载力的理论计算公式.建议公式与试验结果符合较好,可为FRP筋混凝土双向板的设计应用提供必要的理论分析依据.Based on the bending failure characteristic of concrete two-way slab reinforced with FRP rebars,the concept of nominal yield strength and effective cross-sectional area of FRP bars are defined,and the theoretical formula for calculating the ultimate flexural capacity of FRP rebar reinforced concrete two-way slabs by means of plastic ultimate analysis method are proposed.The theoretical formula proposed in this paper correspond with experimental results,which can provide the necessary theoretical basis for the design and application of FRP rebar reinforced concrete two-way slabs.
